Drinking water

Safe, clean drinking water is what we expect when we turn on our faucets. The DNR Bureau of Drinking Water and Groundwater manages activities that affect the safety,
quality and availability of drinking water to protect public health and our water resources.

The vast majority of Wisconsin's municipal water systems disinfect the water they deliver to consumers, killing viruses and bacteria that can
unexpectedly occur in groundwater. Learn if your municipal water supplier disinfects.
